AUTOMOBILE-RADIATOR CONNECTION:

To all whom it may concern: I 7

Be it known that 1, JOHN J. PENHALLE- son, a citizen of the United States, residing at Mineral Point, in the county of Iowa and State of lVisconsin, have invented certain Heretofore in the art'it has been the prac-,

tice to provide a flexible hose extension in the lead from the parts to be cooled to the radiator, and means for detachably securing the opposite ends of the hose in place so that the same might be removed in the case of wear and substitution of another therefor, and also to enable the uncoupling of the radiator to enable its removal from the vehicle. Y l

My present invention includes the form-- ing of the radiator with a separable coupling element adapted to cooperate with a compleniental coupling element connected to the hose or other piping, and improved means for binding the separable coupling membersin sealed relation, said means in turn being of what may be styled a quickdetachable nature. A characteristic of the prefe'Ted embodiment of the invention resides in the fact that though confined within small space or at a comparatively inaccessible place, the same may be readily assembled in operative position and secured in the sealing condition referred tog and a further characteristic is that quick separation may be accomplished upon simply releasing one of several securing devices together utilized in clamping the parts together at separated points. Y

I The preferred embodiment of the invention' to which 111m just referred isillustrated in the accompanying drawings forming part hereof and'the details in the construction and combination of parts may be readily understood from the specific description hereinafter contained when read in connection with said drawings.

In the drawings: p

Figure 1 is an inner face view of a portion of a radiator with my improvements applied thereto i .Fig. 2 is a side view; and;

Figs. 3 and 4 are partly longitudinal sections and side elevations showing-the parts in coupled position and in uncoupled position respectively. I Referring more specifically to the drawlDgS,IVl1l8l11 like reference letters designate corresponding parts in the several threaded collar F on said stem, at suitable packing G being interposed to effect the sealing engagement ifsaid packingis found necessary. Loosely mounted upon the stem E and exteriorly thereof and confined in place by the enlarged end portion H of the coupling member now being described and the nut F is a ring J having oppositely projecting pairs of cars K in which are pivoted as at L clamping bolts M to be again referred to. The complemental separable coupling member has a stem N peripherally roughened or grooved to receive and retain in place by a clamp O the end of a hose section P leading to theimechanical part or parts of the vehicle to be cooled. This stem N is formed integrally with an outwardly extending flange Q, and beyond said flange with a longitudinal tapered or rounded part R constituting the male member of the coupling adapted to fit in the socket C of the other coupling member 13 The end of this projection R is of substantial thickness to bear upon a packing ring S introduced into the socket to occupy a position between the shoulder D thereof and the end of the projection B so that when the coupling members are clamped together in a manner as will now appear, the joint will be sealed. Extending outwardly from'the flange Q are oppositely disposed pairs of spaced lugs T integral with the flange Q thespacebetween the member of each pair of lugs opening outwardly or peripherally to permit the free insertion or removal of the endsof the bolts M when rocked on their pivots L. The outer or free ends of the bolts are threaded to receive thumb or other nuts U, so thatwhen the bolts are thrown between the lugs T and the nuts screwed up against the outer faces thereof, the projection It of the separable coupling member will be.

forced home or against the packing or f washer D to secure the coupling members vision is made to enable adjusting the position of the bolts M to bring them into reg istrationwith the spaces between the lugs and this is primarily the purpose for the v loose ring J that carries said bolts, it being instantly appreciated that the ring may refvolve about the stem E at the will of the operator. Another reason for this special arrangement is that the threaded portions of the bolts M and their pivots L are perhaps the weakerelements of the device and when desired to substitute new bolts in theirstead it is simply necessary to remove the coupling member which is normally fixed to the radiator,'take off thenutF and slip the ring II with" its bolts from the coupling member when another may take its place. A further advantage of this construction is that, as

hereinbefore observed, these parts are sometimes arranged in inaccessible places and the ease with which the hand of the operator may bring the bolts into alinement with the spaced lugs T is a matterof consequence.

-In clampingthe' coupling members to? gether of course both bolts are properly engaged with the lugs of the outer or separable coupling member, and the nuts turned up to rigidly clamp the coupling members together. However, in removing the coupling it is not necessary that both nuts be loosened because upon the loosening of say the upper nut, the conical formation of the projection R will permit the outer coupling member to rock downwardly thereby throwing the lowermost lugs T toward the outer coupling member or radiator whichwill permit the lower bolt to fall from place and entirely release the hose section from the radi ator. Again, after once adjusting the parts,

the connecting of the hose member to the radiator may be accomplished by simply inserting the lower lugs in advance of the nut over the-boltusing the same as a fulcrum for rocking the projection R back into im pinging relation when the upper bolt may be dropped into position and clamped. Here, 7
